To all lv/wm it may concern.' 1

Be it known 'that I, FRIEDRICH WILHELM KnrTNnn, a subject of the German Emperor, and residing4 at Altona, Prussia, Germany, have invented certainnew and/useful Improiff'ements in `Apparatus for Dividing More or Less Thick Liquid orPasty Materials-*- for Instance, Chocolate and lthe like-of which the following is a specification.

The machines for dividing materials such as chocolateand the dlike known heretofore generally have'a reciprocatingpiston working beneath a cylinderinto which the material is fed by a closing valve. p f

Machines otthisdescription are so con'- structed that either Y very thick Huid or pasty materials forthat-materials of a more liquid state can be treated. In the first instance outward motion of the piste-nis Obtained `by `the pressureoi' the material itself and only `the inwardinovement is `brought about by the' aid yof some other moti-ve power.` f, For the outward movement the positivedrive is not desirable on account of the liability of forming hollow spaces, `which necessarily `must be created when the piston moves at a greater speed, than the incoming material. When thin liquid material is used it is notpossible to move the piston by pressing forward the material. `The feed of thematerial isfproduc-ed by the aid of a worm arranged within the feeding funnel, whichworm cannot push the `mass `forwardwhen it is thin. lnsuch cases it is necessary to drivefthe piston positivelyin both directions, which can be done without inconvenience, since in using thin liquid materials there is no fear'oil creating hollow spaces. i f

f From the above it will be `understood,that it is impossible totreat thick liquid materials as wellas ythin liquidmaterials with one and the same machine .as known heretofore without changing the construction of the machine to a considerable extent/and this cannot `bedone without heavy costs. A According to the present inventiony means f are provided fory to rallow-the piston to be driven either positively or bythe aid ofthe advancing `material according to need; This object in view two horizontally movable pis-` tons are used, which are operated by a .common reciprocating member, `which iskreleashas the advantage that the ement of the conveyer apronA can rbey held the cams Z there is a `motion of the rod z' ably connected with the pistons in such manner ton is produced by the said member while at the'movement of this inemberin opposite direction the piston may be leftto itself so asto carry out its outward movement by the action of the advancing material.

The new machine-may be provided with a conveyer apron or endless band which carries the material (divided into portions) in dishes or rtrays away and whiclris .operated by the driving Vmeans of the pistons. This feedingr movethat each forward movement of the pis-4 GERll/IANY, ASSIGNOR TO THE FIRM 0F synchronously with the operation of the f piston.-` Moreover an adjustability is provided forte change the stroke of the pistons,

whereby also the feedingr movement `oi the conveyer apron is changed correspondingly.

The amount'of the material divided off each time and the length of the trays should `be 'ma certain proportionto one another.

In the drawings amachine is shown constructed according to the present invention by way of example. v

Figure l yis a sectional elevation of the I machine and FigzQ an end view of the same. Figs. 8-6 represent details of the machine.

1n the machine shown the material is'ied into "the funnel a. within a lower prolongation otwhich a feeding worm b is arranged, which feeds the material tothe rotatable valve c. the cylinders f within which work the pistons e. The piston rods e are operated by driver arms g, ,which are mounted on areciprocating sectional rod or spindle z. The two seetionsof the spindle are threaded `at their inner ends left and right handed 4and are connected by a correspondingly left and right hand nut it. Parallelto the spindle c' a driving shaftis jonrnaled carryingtwo camsaZ, whichfarefarranged in such complementary position, that when the shaft 7c rotates the sectional spindle z' is moved ylongitudinally in one` or the other direction by the cams operating the rollers t arranged on the rod t'. lThe distance between the rollers z" is such that on a revolution of certain amount of lost tons will always be brought close up to the valve c at an end position, while on and therefore the pisleo l the vmaterial downward thus allowing it to merely by the piston is moving toward the valve c;

the return Y movement the` corresponding arm g allows the piston e to stay behind, so. that the latter can bek moved loutward the advancing material.

the latter is in such a position that it directs be pressed out through the nozzle c.V

Should it be desired to give the kpiston in Vboth directions a positive movement it is only necessary to apply a suitable nut (m, to the piston rod e as shown in Fig.V 3a,

' which tirniiy Connects the. ann g with the piston c. This connection` is brought; about when thin liquid' massis to. b e divided, t

in order to Change. the distance between the two rollers i endthfeieby altertheout- 'ward stroke of thepistons the right and left handed nut Y?, is provided witha wormwheel n whioh is "prevented izom rotating yon the; nut by ,a sliding keyand. notch a',

at: .the saine tiineallowing of a longitudinal Inotion .ofthe nut, the Worm-wheel .being held' between two iangesn xed to, the training; of the machine'. The wormrwheel Vcan be` rotated by .aworm n3" which is providedwitha hand-wheel n4; Thegnut L isfmor'eover providedl with two flanges 0,'

between which an, eye o looselyy surrounds the spindle/z', The eye of is connected. with a rack oy which engagesL a tooth-wheel: p. The latter -is providedwith a crankdisk: g,

which serves for `operating al ratchet mecha:

nism 1i., which in connection with ther drumY o operates the conveyer aprono. vPreferably the disk g isy provided with'. twocrankpins 's and t which areconnected Awith' the pawls 1". of the ratchet mechanism a" f and r2 of the ratchet mechanism r3 respectively by the two'rods s and't. The two ratchet devices '11,.11'and r2, r3 are equally constructedand are operated on every. there and back motion ,of the nut h to move'the conyeyer apron` u, on which" the operator places thefemptyftrays at one end', to an extent, corresponding to the amount of; ma-

teriallfed 'by one piston. Y. v

The; crank-pins s and 15` may be arranged adjustably on the disk g. This adjusta.- bility isarrived at by two blocks w (Fig. 4)', which Aare adapted. to slide within. a guide notch fw running diametrically across; the disk. g and which can be adjusted by-a screwspindle x having right and left handed thread; Thisscrew spindle is preferably provided with a hand-wheel y by'. the

v rotation of which.v the stroke of the ratchet Y.

devices can be changed at: will. f

The cam Z for rotatingfthe valve c-is arranged on the shaft if: in a plane centrall to the-.cams Z.y The cam d` is'vadapted to operate a stud or. pin d lon the arm d of the valve 0. The cam. notch,fintowhich the pin CZ projects has two oblique surfacesd3 and twor straightvsurfaces d4 (Fig. 6)'-so Then as to give the valve c a rest after a quick rotation during the movements of the pistons.` f 1 j By rotating. the hand-wheel/n,4 evidently the VVstrole'rof thefpistons e Vand therefore the lfeed of thematerial aswell as the feed vof the conveyer apronk u' is' adjusted so that the desired synchronism is maintained at all events. v
